What you get with the set

Gatorback Plate Finishes

Here are the different plate finishes

At a glance

Overall sentiment is overwhelmingly positive: customers consistently describe Gatorback/SharpTruck mud flaps as premium, heavy-duty, great-looking products that provide excellent protection, with standout customer service and warranty support; the main negatives are high price and occasional installation/hardware/fitment frustrations.

What Customers Liked

  • Thick, heavy rubber with a substantial feel; durable, flexible in cold/snow/ice; doesn’t “sail” at highway speeds; plates/weights feel robust and can be replaced/swapped.
  • Significantly reduces rock chips, mud/salt spray, and slush on rocker panels, running boards/power steps, bumpers, trailers/RVs; many note cleaner sides and less debris noise on gravel roads.
  • Vehicle-specific fit often described as ‘like a glove’/OEM; finishes (chrome, gunmetal, black plates) and logo plates (Z71/AT4X/FX4/Ram/Ford/Chevy, flags, etc.) ‘make the truck pop’ and draw compliments.
  • Many report straightforward installs, especially after the first flap; helpful YouTube videos; slotted holes help leveling; adjustable stick-out; removable lower section appreciated for off-roading/clearance.
  • Fast shipping is frequently praised; responsive support for exchanges/mis-shipments/damaged parts; hassle-free warranty replacements (torn/ripped flaps or scratched plates) often sent quickly.

Things to Consider

  • Most common complaint: ‘pricey/overpriced’ (often $600–$1000 with brackets/plates). Some feel brackets/plates should be included at that price.
  • Installs can be time-consuming or awkward (especially rears/dually setups), sometimes requiring wheel removal, right-angle drill, extra hands, drilling into plastic liners, trimming liners/trim pieces, or drilling/slot-cutting templates.
  • Paper instructions sometimes lacking, confusing, or mismatched vs video; hardware bags not well-separated/labeled; left/right not always marked; templates/printer scaling issues; ‘no-drill’ marketing criticized when drilling plastic is required.
  • Occasional reports of cheap/fragile fasteners, plastic clips/nut inserts pulling out/stripping, mixed metric/SAE heads, silver hardware being visually noticeable, bracket thickness/material concerns (plastic/galvanized vs stainless), and clamp-on brackets potentially rubbing paint (suggest PPF/tape).
  • Some vehicles need hole elongation, bracket bending, or ‘gerry-rigging’; occasional rubbing with oversized tires/offset wheels; a few reports of mis-shipped parts (two rears), wrong plates/colors, missing washers/spacers/clips/screws, or shipping scuffs/scratches/damaged boxes.

Perfect

You have to get these brackets!! Everything fit perfect. The accuracy of this design was awesome. I’m usually disappointed in the alignment, fit and finish of products like this. Not this time! Went together perfect and made installing a snap. Probably 30 minutes installing the first side and 15 on the second side. Easy!

Truck Hardware Gatorback Black Wrap High Country Dually Mud Flaps - Set

For those who demand premium protection with a touch of sophistication, the Truck Hardware Gatorback Black Wrap High Country Dually Mud Flaps are the perfect choice. Specifically designed for the 2015-2019 Chevy Silverado 3500 HD (Dually Rear Wheel) models, these mud flaps offer unparalleled defense against road debris while elevating the appearance of your truck with the iconic High Country logo on a sleek black background. These mud flaps combine high-quality materials with precise engineering, resulting in a rugged yet stylish upgrade for your vehicle.

Crafted from heavy-duty virgin rubber, the Gatorback Black Wrap High Country Dually Mud Flaps are built to withstand the toughest conditions while maintaining flexibility and resilience. Each rear flap weighs 10 pounds, ensuring they stay securely in place even at highway speeds, preventing 'sailing' or movement out of position. These mud flaps are designed for maximum coverage—5 inches for the front and 9.5 inches for the rear—offering effective protection against rocks, dirt, and road grime that could cause costly damage. The officially licensed High Country logo is die-stamped into a stainless steel plate with a hand-applied vinyl overlay, adding a distinguished and premium look to your truck.

The black wrap finish provides an understated yet sophisticated backdrop for the High Country logo, complementing the rugged design of the mud flaps while also protecting the stainless steel plates from scratches and minor abrasions. This ensures that your mud flaps retain their premium look even after extensive use, giving your vehicle an upgraded aesthetic that lasts.

Installation

Front Flap Installation: The front mud flaps fasten directly to the lip of the wheel well using self-tapping screws, and existing factory fasteners can also be used if available. Installation is straightforward, requiring only basic tools. Make sure you have at least 1/2" of clearance between the tires and the wheel well to accommodate the flap thickness. The front flaps install flush with the wheel well, allowing them to work seamlessly with accessories like step bars, power boards, or side steps.

Rear Flap Installation: The rear mud flaps come with custom-fit Gatorback dually mounting brackets, which are essential for ensuring a secure, stable fit. These galvanized steel brackets provide a robust mounting point, keeping the heavy-duty flaps firmly in place under all conditions. The rear brackets utilize existing factory holes, eliminating the need for drilling into the truck body, though drilling through the mud flaps themselves is required. This method ensures that the flaps are tightly secured, reducing the risk of flapping into the tires. The rear plates, measuring 17 1/4" x 5", provide a bold, distinctive visual element that enhances the overall aesthetic of your truck.

These mud flaps are engineered to provide not just protection but also an OEM-quality look. The High Country logo on the stainless steel plate adds an authoritative finish, giving your truck a polished, professional appearance while maintaining its rugged capabilities.

  • Officially Licensed Chevrolet High Country Logos: Stainless steel plates with hand-applied vinyl overlays ensure a sleek, premium appearance.

  • Sailing: A term used to describe the movement of mud flaps due to airflow, causing them to lift or move out of position, especially at high speeds.
